how to change time limit?

GAMS
1

Hi, everyone,


I took use of GAMS/BARON solver for MIP problem. However, calculation
cannot exceed 1000 sec by the upper limit.

Do you know any method to modify this cutoff in GAMS file? Thank you


cheers

Hi Yan,

I had the same problem. According to the Baron manual, if unspecified
by option, the gams resource limit is enforced.

You can change the termination options using the “option MaxTime =” in
your baron.opt file. In its function it is equivalent to the GAMS
option reslim.

Regards
Chris

Dear Chris,


Thank you for your suggestion, I’ve changed the time limit by
modifying Baron option file.

$onecho > oqnlp.opt
MAXTIME 10000
$offecho

and add

myModel.optfile=1;

before solving the model


Thank you very much


cheers!

cutoff> you can decomposite the mathematical model or you can change
the options that change the calculation upper limit by statements.
Determine which method you choose.?
